3. Purple Loosestrife

Yet another invader--this one is a native of Europe, Asia, Northeast Africa, and southeastern Australia. I knew it was considered an invasive species (at least here in rainy New England), but now I know where it's from originally.

Whoo! No wonder this plant (Lythrum salicaria) is taking over--it's natural predators are still overseas, and each plant can produce up to 3,000,000 seeds per year. Unfortunately, native plants such as cattails are being completely crowded out in some areas. But biological control in the form of the introduction of insects that will prey on the plant's various parts has been implemented with some success.

Still, rivers and ponds with these pretty purple flowers surrounding them are a lovely sight to behold.

Yes--I want to get down to the pond and take some good shots of the water plants! I was focusing on getting the blooming plants while they are still blooming. Didn't see any water lilies, but will look extra hard next time.

About the 100 Species Challenge

Learn to identify one hundred species of flora within walking distance of your home! scsours began this challenge in July of 2008, and I was eager to hop on the bandwagon about a month later. I've remembered much and learned even more. It's been a fun but slow process. Spring has finally arrived here in Massachusetts, and I will hopefully be posting often soon.
